A new experimental device has been developed to investigate creep forces between wheels and rails. The device — called the Creep Tester — is applicable to existing rails, and its wheel is capable of rolling on rails while using a specific mechanism to alter any longitudinal creepage generated. The Creep Tester is also equipped with a mechanism for setting wheel yaw angles to induce lateral creepage. Along with a number of other features (including a short measuring time and the ability to set normal forces), the device is advantageous in ascertaining the parameters that affect creep force characteristics.
